Description

Technical Field

[0001] This utility model relates to the field of hydraulic pump technology, and in particular to a hydraulic pump structure with a filtration function. Background Technology

[0002] The basic working principle of a hydraulic pump is to use changes in the sealed volume to draw in and pressurize oil. When the sealed volume of the pump increases, a partial vacuum is created, and the oil in the tank enters the sealed volume under atmospheric pressure, which is the oil suction process. When the sealed volume decreases, the oil is squeezed, the pressure increases, and the oil is forced out through the drain port, realizing the oil pressurization process. According to the structural form, it can be divided into gear pumps, which consist of a pair of meshing gears, have a simple structure, strong anti-pollution, and low price, but have large leakage, high noise, large flow pulsation, and non-adjustable displacement; vane pumps, which have smooth operation, low noise, and higher working pressure and volumetric efficiency than gear pumps, but have a more complex structure; and plunger pumps, which can work under high pressure in high-power hydraulic structures, but have a complex structure, high material and machining precision requirements, high price, and high requirements for oil cleanliness.

[0003] Maintaining the cleanliness of the hydraulic oil in a hydraulic pump is crucial. Dust, metal shavings, and other impurities mixed in the oil will accelerate component wear, increase clearances, reduce pump volumetric efficiency and performance, shorten pump lifespan, and cause component jamming, affecting normal operation. Current technologies often use return oil filters installed on the return oil line of the hydraulic system to filter impurities in the oil returning from various system components to the tank. These filters remove impurities before the oil returns to the tank, preventing them from accumulating and re-entering the structure. However, the installation of return oil filters often involves directly connecting them to the pipeline using tools. When cleaning is required, the connection between the filter and the pipeline needs to be disassembled with a wrench, reducing practicality and maintenance efficiency. Utility Model Content

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, by inserting the installation tube into the filter tube and inserting its bottom into the positioning groove, the positioning frame is simultaneously driven to the designated position.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see the appendix Figure 2 - Appendix Figure 4 This utility model provides an embodiment of a hydraulic pump structure with a filtering function, including a hollow pump body 1. A liquid delivery pipe 3 is connected to the right side of the hollow pump body 1. The hollow pump body 1 is used to support and install the remaining structures. An installation pipe 6 is connected to the top of the inner wall of the liquid delivery pipe 3. The liquid delivery pipe 3 is used to transport liquid. An inlet pipe 9 is connected to the bottom of the inner wall of the liquid delivery pipe 3. A positioning groove 8 is formed at the top of the inlet pipe 9. A filter pipe 5 is slidably connected to the inner wall of the positioning groove 8. The inlet pipe 9 is used to introduce external liquid into the liquid delivery pipe 3. A positioning frame 4 is fixedly connected to the outer wall of the filter pipe 5. The right end of the infusion tube 3 is rotatably connected to a rotating disk 14. Multiple rotating rods 12 are rotatably connected to the right side of the rotating disk 14. The rotating disk 14 is used to drive the multiple rotating rods 12 to move. Multiple limiting rods 13 are fixedly connected to the right side of the rotating disk 14 near the edge. The inner wall of the positioning frame 4 is provided with a slot 27. The limiting rod 13 is used to limit the rotation angle of the rotating rod 12. The bottom four corners of the hollow pump body 1 are rotatably connected to a balancing mechanism 2. The balancing mechanism 2 is used to keep the water pump running horizontally. The rotating rod 12 can be inserted into the slot 27 as the rotating disk 14 rotates.

[0033] Specifically, the inlet pipe 9 is the inlet channel for liquid to enter the hydraulic pump. The positioning frame 4 supports and positions the filter pipe 5. The positioning groove 8 guides the filter pipe 5 into the installation pipe 6 after it is inserted, thus completing the initial positioning during installation. The limiting rod 13 limits the rotation angle of the rotating rod 12 to prevent it from rotating too much and disengaging from the locking groove 27. The locking groove 27 can engage with the rotating rod 12 to limit the position of the positioning frame 4. The main function of the balancing mechanism 2 is to maintain the horizontal state of the water pump during operation and prevent uneven stress on the internal components, which would accelerate wear.

[0034] Please see the appendix Figure 3 Appendix Figure 5 The balancing mechanism 2 includes a universal joint 205, the outer wall of which is rotatably connected to the bottom of the hollow pump body 1. A connecting rod 202 is rotatably connected to the outer wall of the universal joint 205. The connecting rod 202 is used to connect the universal joint 205 and the rest of the structure. A second universal joint 206 is rotatably connected to the bottom of the connecting rod 202. A base 201 is rotatably connected to the bottom of the second universal joint 206. The second universal joint 206 is used to rotatably connect the bottom of the connecting rod 202 and the top of the base 201. A plurality of lead screws 207 are threadedly connected to the inner wall of the base 201. An inclined block 204 is provided on the outer wall of the lead screw 207. An inclined block 203 is fixedly connected to both the front and rear sides of the hollow pump body 1. The lead screw 207 can drive the inclined block 204 to move by rotating.

[0035] Specifically, when the lead screw 207 rotates, the second inclined block 204 can move along with the rotation of the lead screw 207. The base 201 is the supporting foundation of the balancing mechanism 2, ensuring that the hydraulic pump can be stably fixed on the ground when placed, preventing slippage due to external forces. The two ends of the connecting rod 202 are connected to the first universal joint 205 and the second universal joint 206 respectively through rotating connectors, so that the connecting rod 202 can rotate at a certain angle in different directions, thereby adapting to various angle changes when the hydraulic pump is adjusted to a horizontal state. The forward movement of the second inclined block 204 will generate an upward thrust on the first inclined block 203, thereby raising the front side of the hollow pump body 1. By adjusting the rotation angle and direction of each lead screw 207, the operator can precisely control the height of each part of the hollow pump body 1 until the hydraulic pump reaches a horizontal state.

[0036] Please see the appendix Figure 4 - Appendix Figure 6A reinforcing plate 16 is fixedly connected to the front side of the hollow pump body 1. A drive shaft 18 is rotatably connected to the inner wall of the reinforcing plate 16. The reinforcing plate 16 is used to reinforce and support the installation of the drive shaft 18. Mounting plates 23 are fixedly connected to the left and right sides of the base 201. Multiple screws 21 are threadedly connected to the inner wall of the mounting plate 23. Washers 22 are provided on the outer wall of the screws 21. The mounting plate 23 is used to fix it to the mounting surface by the screws 21. A rotating handle 24 is fixedly connected to the left end of the screw 207. A drive gear 17 is fixedly connected to the front end of the drive shaft 18. The washer 22 can increase the contact area between the screws 21 and their bottom. A drive gear 26 is fixedly connected to the rear end of the drive shaft 18. The rotation of the drive shaft 18 can drive the drive gear 26 to rotate.

[0037] Specifically, when screw 21 is tightened, washer 22 is compressed, filling the tiny gap between screw 21 and the mounting surface, so that the tightening force of screw 21 is more evenly distributed on the mounting surface, reducing the pressure concentration of screw 21 on the mounting surface, avoiding damage to the mounting surface due to excessive local force, and preventing screw 21 from loosening. Rotating handle 24 makes it easier for the operator to rotate screw 207, improving adjustment efficiency and operational comfort.

[0038] Please see the appendix Figure 1 - Appendix Figure 3 A driven gear 25 is rotatably connected to the middle of the inner wall of the hollow pump body 1. A liquid outlet pipe 15 is connected to the left side of the inner wall of the hollow pump body 1. The driven gear 25 can be driven to rotate by the drive gear 26. The liquid outlet pipe 15 is used to discharge liquid from the pump. A rotating shaft 7 is fixedly connected to the middle of the right side of the rotating disk 14. A rotating handle 10 is fixedly connected to the right end of the rotating shaft 7. The rotating handle 10 is used to help rotate the rotating shaft 7. A rubber sleeve 11 is fixedly connected to the outer wall of the rotating handle 10. A reinforcing plate 19 is fixedly connected to the right side of the hollow pump body 1. Multiple screws 20 are threadedly connected to the inner wall of the reinforcing plate 19. The rubber sleeve 11 can increase the friction of the outer wall of the rotating handle 10.

[0039] Specifically, the friction between the rubber sleeve 11 and the hand can effectively prevent the hand from slipping and has a certain cushioning effect, which can reduce the operator's hand fatigue during long-term operation. During the operation of the hydraulic pump, the liquid enters the hollow pump body 1 after filtration. Under the action of the driven gear 25, it is compressed and transported. When the liquid reaches a certain pressure, it will be discharged from the pump through the outlet pipe 15 and transported to the pipeline that needs the liquid. The reinforcing plate 19 can effectively withstand the force and torque generated by the rotating shaft 7, prevent the hollow pump body 1 from deforming and being damaged, and ensure the normal operation and service life of the hydraulic pump.

[0040] Working principle: When it is necessary to filter the liquid entering the infusion tube 3, first connect the pipe and the inlet pipe 9, then insert the filter tube 5 into the inner wall of the installation tube 6 and lock its bottom into the inner wall of the positioning groove 8. At the same time, drive the positioning frame 4 to slide to the designated position. Then rotate the rotating handle 10 to drive the rotating shaft 7 to drive the rotating disk 14 to rotate. This drives the rotating disk 14 to rotate, which in turn pushes the rotating rod 12 to move to both sides under the limit of the limiting rod 13, thereby locking it into the slot 27. When the liquid enters the positioning groove 8 through the inlet pipe 9, it will be filtered by the filter tube 5, leaving impurities on the inner wall of the filter tube 5. When it needs to be cleaned, simply reverse the operation.

[0041] When the pressure pump is installed, the base 201 is first fixed in the required position with screw 21. Then, according to the tilt angle of the hollow pump body 1, the lead screw 207 is rotated so that the inclined block 204 moves on its outer wall so that it can fit against the bottom of the inclined block 203. As it moves, the inclined block 203 is pushed to tilt the hollow pump body 1 to one side. At the same time, the connecting rod 202 will rotate synchronously with the rotation of the hollow pump body 1 through the universal joint 205 and the universal joint 206, thereby maintaining the support and limiting of the hollow pump body 1.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
